FIRPTA (Foreign Sellers)

FIRPTA: the buyer withholds 15% of the gross sale price when a nonresident sells US property. It is an advance deposit, not the final tax.

Non-Resident Capital Gains

Nonresident sellers pay US capital gains tax (generally 15-20%) on the net gain via Form 1040-NR; FIRPTA withholding is credited.

Non-Resident Rental Tax

Nonresident rental income is taxed at 30% of gross by default, or on net income at graduated rates via a Section 871(d) election (W-8ECI).

Estate Tax (Non-Resident)

Nonresidents get only a $60,000 US estate-tax exemption (vs $13.99M for residents); US property above it is taxed up to 40%. Treaties may help.

ITIN Requirement

Nonresidents without an SSN need an ITIN (Form W-7) to file US tax returns, claim FIRPTA refunds, and report rental income.
